Topic: Brass Temp Sensor Holder (Read 518 times)

I've tried searching the forum...Years ago I installed a brass temp sensor holder on my '02 Stone after recommendations from the board. Included in the installation tips was to put a dab of heat conducting paste on the tip of the sensor to insure contact with the bottom of the holder.I have another holder that I want to install on my '03 EV-T but have forgotten the type of paste that was recommended and I used. I believe it was some sort of copper type but also remember that some may have recommended anti-seize paste.Looking for recommendations to assist my ageing memory.

BTW - I had a machinist friend turn down a socket to fit into the recess to allow removal of the original when I did the Stone. It'll be available for loan if anybody has a need after I do the EV-T. PM me if needed.

The Instrument Tech in me says it will make little difference between dry and with heat transfer media, a second or two perhaps. We never use anything in industrial temperature sensors although thermocouples are often sprung loaded but there is a considerable mass of metal radiating the heat away.

The thermal conductivity of brass would more than compensate over the plastic variety.

FWIW, I didn't use anything in my Centauro. The Kid was having problems with his Greenie at the time, and I mentioned using the thermal paste with his plastic gizmo. He said it made a big difference.. not particularly *good* at that stage of tuning.. but a difference. I think he eventually went to the brass sensor holder.

The plastic holder has a copper base insert for heat transfer from the head. There is an air gap between the sensor and the holder. I used about a small pea sized dab of copper anti-seize on the end of the temp sensor.
